Patented Jan. 8, 1935 LUBRICATED TWISTED RING William 0. Aldrich, Whitinsvllle, assignor I to Whitin Machine Works, Whitinsville, Mass.,

a corporation of Massachusetts Application March 5, 1934, Serial No. 714,052 1 Claim. (01. 118-59) This invention relates to twister rings and more particularly to the lubrication thereof. The invention further relates to twister rings of the vertical flange type designed for twisting heavy It has been found that the friction developed between the rings and the travelers when twisting heavy yarn causes very rapid traveler wear unless provision is made for lubricating the contacting. surfaces of the ring and traveler.

It is the general object of my present invention, to provide an improved means for conducting lubricant directly to the inner face of a vertical flange twister ring and indirectly only to 15. the traveler.

A more specific object is to provide means for conducting lubricant to a portion of the vertical flange of a twister ring which is definitely above the area of bearing contact of the traveler with 20 the ring when the traveler is in normal running position.

, My invention further relates to arrangements and combinations of parts which will be hereinafter described and more particularly pointed out 25 in the appended claims.

A preferred formof the invention is shown in the drawing, in which Fig. i is a plan view of a twister ring embodying my improvements;

Fig. 2 is a sectionalside elevation, taken along the line 2-2 in Fig. 1;

Fig. 3 is a plan view of .my invention as applied to a ring mounted in a separate holder;

Fig. 4 is a sectional side elevation, taken along 35 the line 4-4 in Fig. 3;

Fig. 5 is a partial side elevation, partly in.sec-

tion, looking in the direction of the arrow 5 in Figs. 1 or 3; n

Fig. 6 is a detail sectional planview, taken 40 along the line 66'in Fig. 5, and Fig. '7 is a partial view similar to Fig. 2 but on a much enlarged scale.

Referring to Figs. 1 and 2, I have shown my invention embodied in a twister ring 10 of the vertical .flange type which is mounted in a shouldered recess or opening in a ring rail 11.

In Figs. 3 and 4, the ring 10 is mounted in a separate holder 12 which in turn is mounted in 24 (Figs. 1 and 2) in the ring rail 11 or 25 (Figs.

3 and 4) in the holder 12. The pocket 24 is shown as being of circular cross section, while the pocket 25 is substantially elongated. For the Purposes of my present invention, the exact shape 6 or section of the oil pocket or chamber is immaterial.

.A matter which is of prime importance, however, is the particular location of the groove or recess 20 in the inner face of the vertical flange 10 of the ring 10. The groove 20 must be so located that it is above the area of bearing contact of the traveler T with the ring 10, when the traveler is in normal running position as indicated in Figs. 2, 4 and 7. As the groove is above the area 15 of bearing engagement, the oil is delivered by the wick directly to the inner surface of the ring 10, and then works downward indirectly to engage and lubricate the traveler T.

The ring becomes heated during the twisting operation, thus raising the temperature of the oil and increasing its fluidityyso that this indirect method of lubrication is found to be very efl'ective and satisfactory.

It is of particular importance that with the described construction the wick W is at all times out of direct contact with the traveler'T. so that it is not subject to wear thereby and remains 0 much longer in satisfactory operative condition.

becomes hardened and thereafter ceases to satisfactorily" perform its required function.

The delivery of the oil directly to the inner face of the ring by the wick W and indirectly only to the traveler T provides muh better control of the amount of lubricant than in constructions where the traveler removes the oil directly from the wick. In that case, the traveler is overlubricated by a new wick, but not sufllciently lu- 40 bricated by a wick, which has been in service.

'- I thus lubricate the inner surface of the ring to such an extent as to greatly reduce the friction of the traveler T, while at the same time I avoid a widely fluctuating oil supply,.and particularly the excessive supply of oil delivered by a new wick when directly engaged by the traveler. Excessive oil in lubricating rings is almost as objectionable as a deficiency of oil, as the excess oil accumulates on the floor under the machine, thus creating a fire hazard, and also very ply will be maintained substantially uniformfor long periods of operation.

Having thus described my invention and the advantages thereof, I do not wish to 'be limited 5 to'the details herein disclosed, otherwise than as set forth in the claim, but what I claim is:-

' In a twisting machine, a ring having a vertical traveler flange with a relatively short recess in its inner vertical face and with an opening extend- .l0 ing outward through said flange and communicating with said recess, a wick extending continuously through said opening and recess, and an oil pocket located externally of said ring and into which an end of said wick extends, and atraveller, said traveller only engaging the inner I surface of the ring below said opening, and said wick delivering oil directly to the inner upper surface of said ring above the area of bearing engagement of the traveller, whereby oil is fed indirectly only to the traveller.
